Gateway laptop - blank screen upon boot

Issue

I have a Gateway model-M-6332 laptop. When I turned it on, the screen remains blank.

Solution

Try this:
1. Take out the battery
2. Plug in the cable
3. Restart the laptop by pressing the start button while holding it for 62 seconds.
4. It should start, then you can put the battery back in.
Thanks to bionik for this tip.
